T-Halow P4 get it now

Overview

T-Halow P4 is a high-performance IoT development board based on ESP32-P4 (16 MB Nor Flash QSPI, 32 MB package-stacked PSRAM), co-processor ESP32-C6-MINI (Wi-Fi 6 + Bluetooth 5.3, SDIO), and T-Halow module (Wi-Fi HaLow 802.11ah, 730–950 MHz). Features MIPI-DSI display interface, MIPI-CSI camera interface with H264/JPEG encoding (1080P), Pixel Processing Accelerator (PPA), and 2D DMA. The ESP32-P4 handles complex graphics and video tasks while the ESP32-C6 provides Wi-Fi 6 and Bluetooth 5.3 connectivity via esp-hosted-mcu over SDIO. Primary development platform: ESP-IDF v5.4.1+.

T-Halow-P4 and T-Halow use the same AT Command Set.

ESP-IDF (Primary)

1. Install Visual Studio Code and the ESP-IDF extension
2. Install ESP-IDF v5.4.1+
3. Clone the T-Halow-P4 repository
4. Build and flash:

   cd examples/xxx
   idf.py set-target esp32p4
   idf.py build
   idf.py -p PORT flash

Enter Download Mode:

1. Plug in USB, hold BOOT without releasing
2. Press RST briefly, then release
3. Serial output "wait for download" → in download mode
4. Release BOOT, then flash

FAQ

• Q. How do I enter download mode? A. Hold BOOT, press RST once, release RST while still holding BOOT, then flash with idf.py flash.

• Q. Which ESP-IDF version is required? A. ESP-IDF v5.4.1 or newer. Configure and build with idf.py set-target esp32p4.

• Q. What frequency bands does the HaLow module support? A. 868 MHz (859–894 MHz) and 915 MHz (902–928 MHz). Select appropriate band per regional regulations.
